Ramp Block (Ramp Function) - GE AV-300i User Manual

1.7.3 Ramp Block (Ramp Function)

The Function of this Block is to generate the Ramped Speed reference. Such signal is generated by tracking the
reference of the Ramp Setpoint Block with the Ramp times defined in the Multi Ramp Block.
The Block allows to select the source origin on the input:
Ramp input = 0 which allows to obtain the input zero setting, Ramp output = 0 which allows to obtain the
output zero setting, Ramp freeze which maintains on the output the reference value independently of the pos-
sible variations on the input.
Furthermore, among the parameters it is possible to configure:
with Ramp shape the ramp type, if a Linear or an S-shaped, with Ramp out enable it is possible to disable the
Ramp output only as a reference, that is blocking the output by keeping the signal active.
When the Drive is enabled, the Block has at its disposal the Catch on the fly function, capturing a rotating motor.
The function allows to detect the motor speed and to set the output of the Ramp Block at the same speed as the motor one.
The main application fields are: the reinsertion after an alarm intervention or during the capturing of a motor
already started by a load, etc.
It is possible to monitor the output signal, the output state (if enabled or disabled), the ramp acceleration or
deceleration state and the command state.
The inputs of this Block are:
The outputs are:
